CC2530: Communication between coordinator and end device in zstack3.0.1

I see you use broadcast to send messages from coordinator and end device might miss broadcast. You should use unicast.

Hi YK CHen Sir.

Thanks for your reply.

I have some issues.

1)
I can enter IEEE address of end devices through UART in coordinator.

I want that coordinator communicate with registered end deviecs only.

And I want that end devices connect only with coordinator have its IEEE address.

How register IEEE address of end device in coordinator?

2)

And When coordinator don't exist , power consumption of end device change from few uA to 36mA.
If end device connect with coordinator , power consumption of end device is few uA.

what is issue?

Best regards.

YK Sir.

I think that answer of No.1 is e2e.ti.com/.../580981

right?

1. Yes.
2. In Z-Stack 3.0.1, device would stop sending beacon requests when it loses connection with coordinator. If device hasn’t joined any network, it won’t send beacon requests after power on. ZED only start to beacon after you call bdb_startCommission.

YK Chen Sir.

I did understand yours.

#if ZG_BUILD_ENDDEVICE_TYPE
case BDB_COMMISSIONING_PARENT_LOST:
if(bdbCommissioningModeMsg->bdbCommissioningStatus == BDB_COMMISSIONING_NETWORK_RESTORED)
{
//We did recover from losing parent
}
else
{
//Parent not found, attempt to rejoin again after a fixed delay
// printf("PARENT LOST\n");
osal_start_timerEx(EasenLock_TaskID, EASENLOCK_END_DEVICE_REJOIN_EVT, EASENLOCK_END_DEVICE_REJOIN_DELAY);
}
break;
#endif

Once every 10 seconds, power consumption of end device change from few uA to 36mA.

Then resolving method is nothing?

I think that power consumption is too high.

Please give me some advise.

When device sends beacon requests, 36mA is normal and there’s nothing to improve this unless you use a more power efficiency chip.

YK Sir.

I understand.

But I think that keeping time of 36mA is too long.

I think that it't time is about 8 ~ 10 seconds.

is right?

I suppose that’s because ZED is scanning all 16 channels.

If Coordinators and end devices use only one channel, how about?

I think it would reduce to about 1.5 to 2 seconds.

YK Sir.
In ZDO_StartDevice(),

zgDefaultChannelList = MAX_CHANNELS_24GHZ;

is replaced with zgDefaultChannelList = DEFAULT_CHANLIST?

YK Sir.

I misplaced on above.

In ZDO_StartDevice(),

runtimeChannel= MAX_CHANNELS_24GHZ;

is replaced with runtimeChannel= DEFAULT_CHANLIST?

I couldn’t understand your question. Can you elaborate?

YK Chen Sir.

I said "If Coordinators and end devices use only one channel, how about?".

For this, you said "I think it would reduce to about 1.5 to 2 seconds."

So I want that ZED send beacon for 1 channel.

To resolve above problem,What method I use?

My idea is as following.

In ZDO_StartDevice(),

runtimeChannel= MAX_CHANNELS_24GHZ;

is replaced with runtimeChannel= DEFAULT_CHANLIST?

Please send me your advise.

Hi YK Sir.

In order to use one channel in ZED and ZC, I set as following.

#define BDB_DEFAULT_SECONDARY_CHANNEL_SET 0

right?

If right, in other part have issue?
